Ocean forecasting

The Met Office has had a long-term commitment to operational
oceanography, running operational storm-surge models and global
and European wave models.
Through the development and operational implementation of the
Forecasting Ocean Assimilation Model (FOAM), we meet a continuing
requirement for analysis and forecasting of the global ocean in
depth for the Royal Navy. We also run shelf-seas models for short-period
forecast modelling of the north-west European shelf-seas and UK
coastal waters for a wide range of users.
Our ocean forecasting capabilities are outlined below.

The Forecasting Ocean Assimilation Model (FOAM) produces real-time
analyses and forecasts of the temperature, salinity, currents
and sea ice of the deep ocean for up to five days ahead. FOAM
is built around a physically-based ocean and sea-ice models. A
global version of FOAM with 1° horizontal resolution and 20
vertical levels has been run every day since October 1997. In
addition we run a number of nested basin-scale and regional configurations
of FOAM at resolutions up to 1/20°.

| Since June 2000 the Proudman
Oceanographic Laboratory Coastal Ocean Modelling System (POLCOMS)
has been run operationally, daily, by the Met Office. The model
was developed by POL and brought to operational status by the Met
Office. The model is run to produce real-time predictions, out to
two days ahead, of density and current structure over the north-west
European shelf and at the shelf break.

We are applying carbon-cycle and biogeochemical
models for both the open ocean and UK waters. Through inclusion
of the Hadley Centre Ocean Carbon Cycle (HadOCC) model in FOAM,
we are able to make predictions of biological parameters for the
global oceans. For the shelf-seas around the UK we use the MRCS
(Medium-Resolution Continental Shelf) coupled hydrodynamic-ecosystem
model, where the hydrodynamics are supplied by POLCOMS and the ecosystem
component through the European Regional Seas Ecosystem Model (ERSEM),
developed at Plymouth
Marine Laboratory (PML).

For many years the Met Office has run second-generation global
and regional wave models to provide forecasts of sea state, supporting
a range of user applications. There are three operational wave
model configurations, with different areas and resolutions, currently
in use: global, European and UK waters.
